I had the same prob a couple months ago and went to the dealer (under warranty). They said it's not the bulb thats throwing the code but the module. Got the car back the following day and prob solved. Hope this helps.

On all LCI Bi-xenons, the inner two 'spot' lamps are either dummy lights if you don't have adaptives, or they are corner lights if you do have adaptives.

The main/dip beam is only ever the outer single xenon, unlike pre-LCI where the inner light was the halogen main beam.

But back to your question, now we live in the sticks with no street lighting, yes they are very useful, when you slow to turn left or right they light up direclty to the side the verge/footpath/potholes/dead badgers etc so you avoid things you might otherwise hit.

Did you find out which module it was? I'm having the same issue. Getting a cornering light malfunction.. but the h3 bulbs look OK.
This is on a 135... they should be the same.
Car is OOW so no go on going to dealer unless last resort.
This thing came up once or twice while in warranty but it came and went (never showed up on the dealers radar when mentioned). Now the warning is on all the time and the ring on startup is getting annoying.
Thanks.

Hmm... was the bulb obviously bad or how did you test to see if it was bad/good?

I have the exact same message on my dash and I have taken out the bulbs and looked at them... they looked fine... I've also checked to see if they light up while the warning is on and they do. Weird.

Test instructions:
Turn on your engine
Move the steering wheel all the way to your left
Get out of the car and visually inspect that the cornerning light is on
Get back in your car and turn on the steering wheel all the way to your right
Get out of the car and visually inspect that the cornerning light is on

In my case, my passengers side did not turn on just the driver side.
Turned the engine off
Pop the hood
Took the bulb out and presto, the bulb appears fine but their is a hairline wire cut inside the bulb...

I'm going to take another look at them this weekend and see if I can find something I overlooked. When I tested them last time they both worked. I even swapped the bulbs from one side to the other. I hope its not that module.

I gotta take the car in for the battery connection recall soon so if I can't find it I'm sure the dealer will have something to say.

My 2009 e90 has the "cornering lights failure" warning come up about once a month and has done so since new. The cornering lights don't come on when the warning is present, and neither do the xenons adapt by refocussing as speed rises and falls. Shutting the ignition and lights off, then back on again doesn't fix it either, but then next day there's no problem. My dealer reset or reflashed the computer which they thought might fix it, but the warning still intermittently returned.

In 2010 I replaced the bulbs in the cornering lights as a mod to get all front end lights at 6000k. Still the problem persisted and does so today in 2013. My dealership doesn't want to know about it as they know the current bulbs are aftermarket, regardless of the fact it also did it with the original bulbs. I don't want to spend much money on it as it's only intermittent, but it is pretty annoying.
